摘　　要：从能量平衡的观点来研究泥沙的运动规律,是泥沙运动力学中的一个重要研究方向。本文总结了有关学者提出的挟沙水流的能量平衡方程,指出这些方程还存在一些缺陷。从而从这些有缺陷的能量平衡方程所得到的一些泥沙运动理论,如输沙强度、动床阻力等,就难免在理论上存在一定的不足。因而目前应加强挟沙水流的能量平衡方程的研究,才能促进泥沙运动理论的进一步发展。Studying the basic rules of sediment transport from the concept of energy balance is one of important trends in sediment transport mechanics. The energy balance equations of sediment-laden flow has been summarized, and there are defects in various equation purposed by different researchers. Therefore, some sediment transport theories derived from these energy balance equations of sediment-laden flow, such as sediment transport intensity, resistance in movable bed, etc., inevitably have some flaws in theory. The energy balance equations of sediment-laden flow should be intensively studied so as to promote the development of sediment transport theory.
